Abstract
The utility model discloses a kind of Self-locking screw nuts, including screw and the nut being equipped with outside the screw, the radial direction of the nut is provided with the internal thread of multiple perforations, the internal engagement of the internal thread is provided with holding screw, the tapered shape in inner end of the holding screw, and be mutually butted on the screw thread of the screw.The holding screw is made for brass material, and material is relatively soft, the screw thread of screw can not be damaged described in effective protection in use.The utility model improves the self-lock ability of screw-nut, fails so as to avoid component of machine, easy to use, and manufacture is at low cost.
Description
【Technical field】
The utility model is related to the technical field of securing member, more particularly to a kind of Self-locking screw nut.
【Background technology】
Screw and nut can be used often in the connection fastening of numerically-controlled machine tool, be used to machine components being assembled into component
Or whole set equipment.But during the use of lathe, lead to the loosening of nut due to mechanical oscillation often, in turn result in machinery
Parts fail or even lathe damage.Existing Self-locking screw nut type is various, and various self-locking manners emerge in an endless stream, some
Structure is complex, some self-lock abilities are effective, and self-lock ability is poor, there are also being influenced by installation space, mounting means and
Cannot preferably it be applied in numerically-controlled machine tool.
【Utility model content】
In view of this, in order to overcome the deficiencies of the prior art, the utility model provides a kind of Self-locking screw nut, is not changing
Under the fastening means of original screw-nut, self-lock ability is improved, simple in structure, easy to use, manufacture is at low cost.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of Self-locking screw nut, including screw and the nut being equipped with outside the screw, the diameter of the nut
The internal thread of multiple perforations is provided with to direction, the internal engagement of the internal thread is provided with holding screw, the holding screw
The tapered shape in inner end, and be mutually butted on the screw thread of the screw.The holding screw is made for brass material, material
It is relatively soft, it the screw thread of screw can not be damaged described in effective protection in use.
Preferably, the nut is hex nut, it is only necessary to the internal thread is processed on existing standard hex nut,
Easy to use, manufacture cost is relatively low.
Further, the nut is round nut, it is only necessary to the internal thread is processed on existing standard round nut, is used
Convenient, manufacture cost is relatively low.
Further, multiple internal threads axial symmetry centered on the screw is set, after holding screw locking,
It is equally loaded, is not easy to loosen, self-lock ability is stronger.
The beneficial effects of the utility model are：It is improved by simple structure, improves the self-locking energy of the screw-nut
Power fails so as to avoid component of machine, easy to use, and manufacture is at low cost.
【Description of the drawings】
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the vertical view of Fig. 1；
Fig. 3 is the structure diagram of nut in Fig. 1；
Fig. 4 is the use state diagram of the utility model.
In figure, 1, screw, 2, hex nut, 3, holding screw, 4, internal thread, the 5, first part, the 6, second part.
【Specific embodiment】
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Referring to figs. 1 to Fig. 3, a kind of Self-locking screw nut, including screw 1 and be equipped with outside the screw 1 six
Angle nut 2, there are two the internal thread 4 penetrated through, the internal engagements of the internal thread 4 for the radial direction setting of the hex nut 2
Holding screw 3, the tapered shape in inner end of the holding screw 3 are provided with, and is mutually butted on the screw thread of the screw 1.It is described tight
Determine screw 3 and be made for brass material, material is relatively soft, in use can screw 1 described in effective protection silk
Button is not damaged.
Two internal threads 4 axial symmetry centered on the screw 1 is set, after the holding screw 3 locking, by
Power is uniform, is not easy to loosen, self-lock ability is stronger.
As shown in figure 4, in use, screw 1 sequentially passes through the first part 5 and the second part 6, in the lower end of screw 1 screw-in
Hex nut 2, and hex nut 2 is made tightly to fit in the bottom surface of the second part 6；It is screwed in respectively in the two sides of hex nut 2
Holding screw 3, and the inner end of holding screw 3 is made mutually to be butted on the screw thread of screw 1, you can realize the auto-lock function of screw-nut.
The utility model improves the self-lock ability of screw-nut, fails so as to avoid component of machine, easy to use,
It manufactures at low cost.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
